Rehabs That Take Mass Advantage

Does Mass Advantage Cover Drug and Alcohol Rehab?

Yes. As a Medicare Advantage plan it must cover at least what Original Medicare covers, and Medicare pays for inpatient stays in general and psychiatric hospitals, outpatient substance use disorder treatment, partial hospitalization at 20 or more hours a week, intensive outpatient at 9 or more hours a week, and opioid treatment program services. The 2026 Mass Advantage documents set the copays for inpatient psychiatric care and outpatient therapy.

The four plans for 2026 are Mass Advantage Basic (HMO) H7670-001, Plus (HMO) H7670-002, Premiere (PPO) H9904-001 and Extra (PPO) H9904-002. All four are Medicare Advantage plans with Part D attached, covering Parts A, B and D. The Plus (HMO) evidence of coverage also names chronic alcohol and other drug dependence, and chronic and disabling mental health conditions, among the conditions that can qualify a member for special supplemental benefits by self-attestation.

Medical Detox

No Mass Advantage document found addresses withdrawal management directly, so the question for member services is which benefit tier an admission for medical detox falls under and whether it is treated as an acute or a psychiatric admission. Where withdrawal is already acute, an emergency department is the right destination; alcohol and benzodiazepine withdrawal can cause seizures, and emergent admissions need notification within 24 hours rather than authorization in advance.

Residential and Inpatient

Inpatient psychiatric hospital care is covered on all four 2026 plans, with per-day copays for the opening days of a stay and no member cost after that through day 90. Non-hospital residential rehab is not named in the fetched plan documents and is not listed as an Original Medicare benefit, which puts hospital-based inpatient care at the center of the inpatient question for a Mass Advantage member.

PHP, IOP and Outpatient

A partial hospitalization program is a covered service, and every PHP admission requires prior authorization. Intensive outpatient treatment sits in the Medicare benefit at 9 or more hours a week, so an IOP referral is worth pricing with the plan directly. Outpatient individual and group therapy is covered on all four plans with a per-session copay and no stated visit limit.

Does Mass Advantage Need Prior Authorization for Rehab?

Yes for elective acute and psychiatric hospital admissions and for all partial hospitalization admissions. Emergent and urgent admissions need notification within 24 hours instead. The published prior-authorization list does not mention withdrawal management, intensive outpatient, residential treatment or opioid treatment programs, so those are worth raising on the phone before a start date is set.

Medical necessity is decided using CMS National Coverage Determinations, Medicare Administrative Contractor Local Coverage Determinations and the Medicare manuals; where none of those apply, the plan works down a hierarchy of evidence that includes MCG guidelines. Requests come from the program, not the member: the admissions team faxes the inpatient or outpatient authorization request form to 888-656-7783, and the forms sit on the plan’s provider resources page. No behavioral health vendor is named anywhere in the plan, provider manual or forms, so behavioral authorizations appear to run through the plan’s own utilization management.

Does Mass Advantage Cover Out-of-Network Rehab?

On the HMO plans, no, except in emergencies, for urgent care where no network option is available, for out-of-area dialysis, or where the plan has authorized the care; otherwise the member pays the full cost. Basic and Plus require prior authorization for all non-emergency out-of-network services. The PPO plans pay out of network at higher copays and coinsurance, with advance notification recommended rather than required.

How Much Does Rehab Cost With Mass Advantage?

In 2026, inpatient psychiatric care costs $350 a day for days 1–5 then $0 through day 90 on Basic (HMO) and in-network on Premiere (PPO); $210 a day for days 1–6 on Plus (HMO); and $375 a day for days 1–6 in network on Extra (PPO). Outpatient individual or group therapy runs $25 a session on Basic, $15 on Plus and $30 in network on both PPO plans.

Out-of-network psychiatric admissions on Premiere are $350 a day for days 1–5 then 20% coinsurance to day 90; on Extra they carry 40% coinsurance for days 1–90. Out-of-network therapy is $50 a session on Premiere and $65 on Extra. None of the four plans has a medical deductible. The in-network annual out-of-pocket maximum is $6,750 on Basic, $4,750 on Plus, $6,000 on Premiere and $6,750 on Extra, with combined in and out-of-network caps of $9,500 and $10,000 on the two PPO plans. Premiums are $0 on Basic, Premiere and Extra and $95 a month on Plus, on top of the Part B premium.

Those are the sums a program bills without coverage. With a Mass Advantage card the figure that matters is the copay schedule above and the out-of-pocket cap, which is the ceiling on an extended stay. Part D sits separately: tiers 1 and 2 carry $0 copays, the deductible on tiers 3–5 is $200 on Basic, $150 on Plus, $250 on Premiere and $200 on Extra, and annual drug cost sharing is capped at $2,100.

Does Mass Advantage Cover Suboxone, Methadone and Other Addiction Medication?

Yes. On the 2026 formulary shared by Basic, Plus and Premiere, buprenorphine sublingual tablets and buprenorphine-naloxone tablets sit on Tier 2 and buprenorphine-naloxone films on Tier 4, with quantity limits such as 120 of the 8-2 mg strength per 30 days and no prior authorization listed. Naltrexone tablets are Tier 2 with no restrictions and Vivitrol is Tier 5 specialty with a first fill limit.

Methadone and Opioid Treatment Programs

Methadone for opioid use disorder is a Part B benefit delivered through opioid treatment programs rather than a pharmacy fill, and the formulary lists methadone tablets only as an opioid analgesic on Tier 3. Medicare pays opioid treatment programs for methadone, buprenorphine and naltrexone along with drug testing, counseling, individual and group therapy, intake and assessment, peer recovery support and intensive outpatient services, with no copayment at a Medicare-enrolled program. A methadone clinic is therefore billed under the medical side, not the drug side.

Alcohol Medication and Naloxone

Acamprosate is Tier 4 and disulfiram Tier 3, both without restrictions. Naloxone injectables are Tier 2 and the 4 mg nasal spray Tier 3, with Kloxxado, Opvee and Rextovy on Tier 4 and no restrictions attached. Part D criteria apply prior authorization to antipsychotics and benzodiazepines, though that requirement does not apply under age 65.

Checking the Right Drug List

Extra (PPO) runs a separate formulary, so the tiers above were read for Basic, Plus and Premiere only. The 2026 drug list is hosted on AdaptiveRx and the plan does not name its pharmacy benefit manager on its public pages. Sublocade and Brixadi appear neither on the Part B prior-authorization drug list nor in the Part D opioid dependence section, which is a question for member services before a long-acting injectable is started.

Which Rehab Centers in Massachusetts Are In-Network With Mass Advantage?

A program is in network when it holds a contract for the specific Mass Advantage product named on the member card, Basic, Plus, Premiere or Extra, and is licensed by the Commonwealth for the level of care it delivers. Network status is settled on the plan’s Provider and Pharmacy Lookup or by calling the network line on (844) 554-0514, TTY 711. The network is anchored by UMass Memorial Health physicians and hospitals and extends past that system.

Massachusetts has 370+ listed treatment programs, 300 of which accept Medicare, concentrated in Boston, MA, Worcester, MA, Roxbury, MA and Cambridge, MA. Programs that accept Mass Advantage are gathered on the Mass Advantage page, alongside rehabs in Massachusetts and level-of-care pages for Medicare PHP and Medicare MAT. Each listing shows the payments the program says it accepts, its licensing and accreditation, and how far it sits from the nearest airport, so a shortlist can be drawn up before the call that settles network status. Counts updated October 2026.

How Do I Find a Rehab That Takes Mass Advantage?

Start with the Provider and Pharmacy Lookup on the plan’s website, then call member services: (844) 918-0114 for Basic and Plus HMO members and (844) 915-0234 for Premiere and Extra PPO members, TTY 711 for both. Prospective members use (844) 514-0674. Lines run 8 am to 8 pm Eastern, seven days a week from October 1 to March 31 and Monday to Friday from April 1 to September 30.

Because the service area is Worcester County alone, a program outside Central Massachusetts is an out-of-network question from the start, and on the HMO plans that means either an authorization or the full bill. No separate behavioral health, crisis or nurse line is published, so the member services number above is the route for a question about detox coverage or a level of care the summary does not list.

Is Mass Advantage the Same as MassHealth?

No. Mass Advantage is a Medicare Advantage plan with Part D; MassHealth is the Massachusetts Medicaid program. Mass Advantage sells no Medicaid plan and no dual eligible special needs plan, and it is also distinct from Mass General Brigham Health Plan’s Medicare Advantage products. A dual eligible pays nothing for opioid treatment program services received through the state Medicaid program.

What Happens to Mass Advantage Members in 2027?

Coverage ends January 1, 2027, and every member needs other Medicare coverage from that date. UMass Memorial Health runs a free Medicare Resource Center on 844-416-1051, TTY 711, Monday to Friday 8 am to 8 pm between October 1 and December 31, and says its list of 2027 Medicare Advantage plans accepted is still to come. A course of treatment that runs past the new year is worth discussing with the admissions team and the plan together, since authorizations and network contracts both reset with the new card.
